01General information

Description

HMEC-1 細胞(即人類微血管內皮細胞-1)是一種源自人類真皮微血管內皮細胞的不朽化細胞系。該細胞系的開發旨在促進對微血管內皮功能與病理學的研究。 由於 HMEC-1 細胞能夠保留原代內皮細胞的許多表型和功能特徵,因此在血管生物學研究中被廣泛應用。

HMEC-1 細胞表現出典型的內皮細胞標記物,例如 CD31(PECAM-1)、馮·威勒布蘭德因子(von Willebrand factor)和 VE-鈣黏蛋白(VE-cadherin),且當在適當的基質上培養時,可形成類毛細血管結構,模擬體外血管生成。 這使得它們對於血管生成研究具有特別的價值;血管生成是指從現有血管系統中形成新血管的過程,這在生理與病理狀況(如傷口癒合、癌症生長及心血管疾病)中皆屬關鍵過程。

這些細胞亦被用於探索內皮細胞對炎性細胞因子的反應、內皮層的屏障功能,以及內皮細胞與免疫細胞等其他細胞類型的相互作用。HMEC-1 細胞適合進行基因操作,使研究人員能夠探究特定基因對內皮功能的影響,並建立各種血管疾病的模型。

此外,HMEC-1 細胞還作為研究內皮屏障通透性的模型系統,這在藥物遞送以及病原體穿過內皮屏障導致的傳染病病理機制中至關重要。該細胞系的通用性與易用性,使其持續成為微血管內皮細胞生物學與病理學研究的基石。

06Handling and culture

Culture medium
Alpha MEM,含:2.0 mM 穩定谷氨醯胺,不含:核苷,不含:脫氧核苷,含:1.0 mM 丙酮酸鈉,含:2.2 g/L NaHCO₃
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 胎牛血清 (FBS)、10 ng/mL 表皮生長因子、1 微克/mL 氫化可的松,以及 10 mM 谷氨醯胺
Dissociation reagent
Accutase
Subculturing
從貼壁細胞中移除舊培養基,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶使用3-5毫升PBS,T75培養瓶則使用5-10毫升。 接著,用 Accutase 完全覆蓋細胞,T25 培養瓶使用 1–2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8–10 分鐘,使其脫附。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。
Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

07Quality control and cryopreservation

Sterility

透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。

為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
Storage conditions

若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。

Shipping conditions

冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。
